Procedure
2-(2',4'-Difluoro-4-biphenylyl)propionic acid (2 g.), methanol (20 ml.) and concentrated sulphuric acid (0.6 ml.) were refluxed for 16 hours. Excess methanol was distilled in vacuo, the residue was diluted with water and the oil isolated in ether. Distillation gave methyl 2-(2',4'-difluoro-4-biphenylyl)propionate, b.p. 118°-120°C./0.2 mm.
